Emirate of Muhammara
The Emirate of Muhammara, also known as the Sheikhdom of Muhammara (sometimes also called the Emirate of Arabistan or Sheikhdom of Arabistan), was an autonomous emirate in modern-day Khuzestan province in Iran during the late 19th and early 20th centuries, lasting until the then ruler of Iran, Reza Shah, re-established full control over the region in 1925. Officially it was part of Qajar Iran, but the broader Khuzestan region had already enjoyed a large degree of autonomy under the previous rule of the Banu Ka'b (1740–1840), under whom it had become thoroughly Arabized (whence the name Arabistan).
